Apart from the problems considered above arising, in some cases, from the fact that a withdrawal takes effect on receipt of its notification by the other parties, it has been pointed out that the paragraph does not “really resolve the question of the time factor” (ne résout pas vraiement la question du factuer temps), although, thanks to the specific provision introduced at the Vienna Conference in 1969, the partners of a State or international organization which withdraws a reservation know exactly on what date the withdrawal has taken effect, the withdrawing State or international organization itself remains in uncertainty, for the notification may be received at completely different times by the other parties.
Además de los problemas, examinados supra, que puede plantear, en algunos casos, el hecho de que surta efecto el retiro desde la recepción de su notificación por las demás Partes, se ha destacado que "no resuelve verdaderamente la cuestión del factor tiempo".
